Renovating a building of historic interest is a good way to foster preservation. Many tourists to Greece and Italy are surprised to find that Italy south of Rome and on the island of Sicily has far better preserved ancient Greek sites of interest than Greece itself. The historical reason is that in Greece the invading Ottoman Turks sacked and destroyed ancient Greek ruins as best as they could, while in southern Italy the Christians converted ancient Greek temples to churches which by the 1900s became well preserved museums! This history of conversion of an old beautiful church condos is similar in bottom line preservation effect, which is a good thing in my opinion.
That's a very interesting historical note.
